I went through the Travis history a bit, and these seem to be
the flaky ones. The ubuntu one is likely no libsoup patches.
The other one @smcv has partially traced to a GPGME race condition
or something like that.
For the libsoup one; as I say in comments, once we have libcurl, I'd like to
enable that mostly everywhere, which should (hopefully) be more reliable.

I was working on https://bugzilla.redhat.com/show_bug.cgi?id=1393545
and it was annoying that I couldn't know what the new (unsigned)
commit has was until verification succeeded. I could pull it
manually without GPG, but then it'd be sitting in the repo.
Now:
```

This would be more likely to tickle things like

Also, while working on the curl backend, I hit on the fact that curl doesn't
queue (by default, you can enable) and will happily create 20000+ concurrent TCP
connections if you try. Having this test would have made that more likely to
fail.

There are use cases for having a single repo with branches
with different lifecycles; a simple example of what I was
trying to do in CentOS Atomic Host work is have "stable"
and "devel" branches, were we want to prune devel, but
retain *all* of stable.
This patch is split into two parts - first we add a low level "delete all
objects not in this set" API, and change the current prune API
to use this.
Next, we move more logic into the "ostree prune" command. This paves the way for
demonstrating how more sophisticated algorithms/logic could be developed outside
of the ostree core.
Also, the --keep-younger-than logic already lived in the commandline, so it
makes sense to keep extending it there.

libcurl AFAICS doesn't have an API to convert HTTP code ➡️ error

It turns out libsoup strips all whitespace even *inside* a URL. We could do that
for libcurl too but...really, people shouldn't do that. In this test we were
adding the trailing newline into the URL. If someone complains who is using the
libcurl code we can deal with it then.
Closes: #651
Approved by: giuseppe
This is prep for the libcurl porting. `GTlsCertificate/GTlsDatabase` are

file paths as strings, so it's easier to work on both if we move the GLib TLS
bits into the libsoup code.

I was making some other changes in this code, and noticed that we were adding
checksums without object types into the same hash table for metadata. We should
*never* do this with both metadata content objects, since in theory a content
object could have the same hash as metadata.
I don't actually think it's possible in practice for pure metadata to collide,
since they have different structures, but let's do this anyways since it's
conceptually right.

We had a lot of copies of the "echo something 1>&2; exit 1" code even though

For the pending libcurl port, the backend is a bit more
sensitive to the main context setup. The delta superblock
fetch here is a synchronous request in the section that's
supposed to be async.
Now, libsoup definitely supports mixing sync and async requests, but it wasn't
hard to help the libcurl port here by making this one async. Now fetchers are
either sync or async.
Closes: #636
Approved by: jlebon
Working on the libcurl backend, I hit the issue that the trivial-httpd program
depends on libsoup. I briefly considered having two versions, but libcurl is
client only, and moreover trivial-httpd is no longer trivial - it has various
features which are used by the test suite extensively.
Hence, what we'll do is build it as a separate binary which links to libsoup,
and use it during the tests. We *also* currently still provide `ostree
trivial-httpd` since some things use it like `rpm-ostree-toolbox` and the
Cockpit tests.
After those are ported to use some other webserver, I plan to add a build-time
option to drop it.
Closes: #636
Approved by: jlebon
I'm introducing a new binary in a later patch, and it makes
sense to move more things to be common into the common section.
Also I noticed we were missing an inclusion of common `$(AM_LDFLAGS)`, though
AFAIK this doesn't break anything right now.
Closes: #636

The previous commit introduced a single low level API - however,
we can do things in a more optimal way for the curl backend if
we drop the "streaming API" variant. Currently, we only use
it to synchronously splice into a memory buffer...which is pretty
silly when we could just do that in the backend.
The only tweak here is that we have an "add NUL character" flag that is
(possibly) needed when fetching into a membuf.
The code here ends up being better I think, since we avoid the double return
value for the `_finish()` invocation, and now most of the fetcher code (in the
soup case) writes to a `GOutputStream` consistently.
This will again make things easier for a curl backend.
Closes: #636

Conceptually these now lay on top of the core API, and don't reference libsoup.
This is preparation for libcurl porting, but it's also just generally better.

I was having this thought today about making more of the OS readonly,
and ultimately if we got to the point where all ostree operations are
through the repo and sysroot dfds, we could have rpm-ostree be the
only process holding those fds open, and have a read-only bind mount
on top.
Anyways, we're not there, likely won't be soon, but this gets us
closer to being fully fd relative.
Closes: #628
Approved by: jlebon
I only recently realized this was possible. While we're still seeing
leaks in the CI environment for some reason, adding ASAN gives us
use-after-free detection etc., which is obviously still very useful
even if we're not doing leak checking.
Closes: #622
Approved by: jlebon
This conflicts with the ASAN work...and in general, I think I'd like
to make a new format for tests that require root, and have them be
defined to be in mutable containers or VMs.
Our coverage loss from this isn't much because some of these tests
already required `CAP_SYS_ADMIN` which we didn't have in Docker
anyways.
While we have the patient open, parallelize the regular installed
tests.

Unfortunately, introspection uses dlopen(), which doesn't quite
work when the DSO is compiled with ASAN but the outer executable
isn't.
Trying to inject LD_PRELOAD=libasan means the outer executable has to
be leak free...which, yeah, I'm not going to get into running ASAN
today on gjs or pygobject.
So, let's skip those tests - ideally, we still run them in some other
context without the sanitizers. The coverage we have from them is
middling anyways.

This is a migration from the origin version. It's

Due to the way glib-mkenums runs the preprocessor itself, it
doesn't pick up the `AC_USE_SYSTEM_EXTENSIONS()` that we have in

"libglnx.h"` in one of the headers, since it needs the `basename()`
from `string.h` which is only available with `_GNU_SOURCE`.

This is a follow up to conversation on list - in practice, if we're
backing away from summary signing, then it makes sense to remove the
special casing for checksums in deltas around summary signatures.
This is also related to the recent change to enable GPG checking for
commits in deltas - now we have a more coherent story between the
previous pull path and deltas.
I didn't do any performance checking, and while it's slightly annoying
that we're now doing sha256 on the delta content twice (once for the
part and once per object)...sha256 is pretty fast, I think most users
are I/O bound anyways, and it'd drop even farther if we started using
openssl.

The spam in stderr was bothering me, and further at some eventual

The fact that we weren't doing this is at best an oversight, and
for some deployment models a security vulnerability. Having both
`gpg-verify` and `gpg-verify-summary` shows that we were intending
them to be orthogonal/independent.
Lately I've been advocating moving towards pinned TLS instead of
gpg-signed summaries, and if we follow that path, performing GPG
verification of commit objects even if using deltas is more important,
as it provides an at-rest verifiable authenticity and integrity
mechanism.
Content providers which are signing their summary files and/or using
TLS (particularly pinned TLS) for transport should treat this as a
nice-to-have. However, for providers which are serving content over
plain HTTP and relying on GPG, this is a critical update.

Conceptually we've been moving towards having our GPG verification
paths be per-remote. The code internally supports this, but we
didn't expose an API to use it conveniently.
This came up when trying to add a new `gpgkeypath` option, since
right now rpm-ostree manually finds keyrings for the remote, and
hence it wasn't looking at the keypath, and said "Unknown key"
in status.
Adding an API fixes this nicely.

For Project Atomic, we already have RPM signatures which use files in
`/etc/pki/rpm-gpg`. It's convenient to simply bind the OSTree remote
configuration to those file paths, rather than having duplicate key
data.
This does mean that we need to parse the files for verification, so we
end up importing them into the verifier's temporary keyring, which is
a bit ugly, but it's what other projects do.

What in the code is called "scanning" is ensuring (potentially
recursively) have an object, and if not, fetching it. And then if
it's metadata, parsing it and finding new objects to fetch.
This logic has grown fairly complex. What I'm trying to fix
right now is that if we're doing a pull-local to a remote repository
via `sshfs` (FUSE) we still end up scanning, which is inefficient.
We can take advantage of the "commitpartial" logic here - if a commit
isn't partial, it's complete, hence we don't need to scan it.
At the same time, I'm changing the logic here to *always* do scans for
dirtree objects. This will fix cases where multiple commits share
dirtree objects. We have "commitpartial" metadata, but no such concept
of partial/complete for dirtrees.
But, we'll only ever scan dirtrees if we scan commits, which is
what the section above fixes.

Some deployments may want to gate access to content based on things
like OAuth. In this model, the client system would normally compute a
token and pass it to the server via an API.
We could theoretically support this in the remote config too, but
that'd be a bit weird for OAuth as the information is dynamic.
Therefore this cleans up the code a little bit to more clearly handle
the case that the fetcher is initialized from both remote config
data plus pull options.

I was noticing a recent performance issue with checkouts
which seemed to be mostly us going back to doing a `fsync()` on
directories.
Regardless, while looking at that, I saw we were spending time
creating new symlinks. Even though symlinks are small, it's still
better to hardlink them.
Going way back in time, the reason we weren't doing this is
because we were hitting `EMFILE` on ext4, but that was for
gnome-continuous which creates *many* build roots. Even
there though, they're just a cache, and we handle `EMFILE`.
For ostree-for-host-system, we don't expect to have many roots (just 3
at most transiently), so hardlinking symlinks does make sense.
